A cat carrier is a portable container designed to safely transport cats. It typically features a sturdy structure, a secure door, and ventilation holes to ensure airflow. Carriers come in various sizes and materials, such as plastic or soft fabric, making them suitable for different cat breeds and travel needs. Using a cat carrier is essential for trips to the veterinarian or during travel. It helps keep the cat secure and prevents them from escaping in unfamiliar environments. Many carriers also have handles or shoulder straps for easy carrying, making them convenient for pet owners on the go.
